Species dependence of the impurity injection induced poloidal flow and magnetic island rotation in a tokamak
Shiyong Zeng, Ping Zhu, Haijun Ren
Recent experiments have demonstrated the species dependence of the impurity poloidal drift direction along with the magnetic island rotation in the poloidal plane. Our resistive MH…

Enhanced plasma current spike formation due to onset of 1/1 kink-tearing reconnection during a massive gas injection process
Shiyong Zeng, Ping Zhu, Haijun Ren
The formation of the plasma current spike at the end of the thermal quench phase is studied systematically, which is found to strongly correlate to the onset of the 1/1 kink-tearin…

Geodesic Acoustic Mode in Toroidally Rotating Anisotropic Tokamaks
Haijun Ren
Effects of anisotropy on the geodesic acoustic mode (GAM) is analyzed by using gyro-kinetic equations applicable to low-frequency microinstabilities in a toroidally rotating tokama…
